Solution
The correct option is A Fascioliasis
Diagnosis or identification of a particular disease is necessary for its effective treatment. Stool/Fecal matter test is a common method for the identification of diseases that are transmitted through infective organisms/stages present in the fecal matter.
The presence of the eggs of a pathogen in the fecal matter can indicate the presence of a helminth worm in the body and further microscopic studies can confirm the specific type of worm present.
People usually become infected with liver flukes (Fasciola hepatica) by eating aquatic plants contaminated with immature parasite larvae. The young worms travel through the intestinal wall, the abdominal cavity, and finally reach the liver tissue and bile ducts, where they develop into adults that produce eggs.
The eggs laid by adult flukes in the bile ducts are passed out with faeces. Examining the Fasciola hepatica (liver fluke) eggs in stool (fecal) specimens under a microscope can confirm its presence and help in the diagnosis of Fascioliasis.
Common symptoms of fascioliasis include nausea, vomiting, abdominal pain, fever, rash, difficulty in breathing etc. It can also result in the inflammation and blockage of bile ducts, gallbladder and pancreas.
Amoebiasis is caused by the protozoan Entamoeba histolytica and the infection spreads through the release of cysts, and not eggs, in the fecal matter. Thus testing for the presence of eggs cannot indicate the occurrence of amoebiasis.
Malaria is caused by the protozoan Plasmodium which enters the bloodstream through the bite of the female Anopheles mosquito. The pathogen infects the liver cells and red blood cells in the body and resides in the bloodstream, from where they are picked up by mosquitoes to be transmitted to healthy individuals. Thus presence of the malarial parasite can be confirmed by a blood test and not by a stool test.
Elephantiasis is characterised by the swelling of lymphatic vessels in the limbs or genital areas. This is caused due to an inflammatory response against the presence of the filarial worm, Wuchereria bancrofti, in these areas. Thus the presence of this pathogen can be confirmed by a blood or lymph test not by a stool test.
